They rubbed the particles across the surface by hand, and within about 20 seconds achieved a single layer of densely packed particles arranged in a hexagonal pattern. “The rubbing is done using a stamp made of a silicone-like material called PDMS,” says Kai Sotthewes of the University of Twente. “The static electricity generated by the rubbing process, especially on harder surfaces, and the forces between the particles and the surface are crucial for creating the desired patterns. We encounter this static electricity in everyday life, if we rub a balloon against our hair or feel a shock on a dry winter day when we touch a metal object.”
